Principles of PIN and Avalanche Photodiode (APD) detectors, receiver configurations, and noise performance analysis. Key System Considerations
The later chapters touch on coherent detection, solitons, and wavelength-division multiplexing (WDM)—presciently predicting Dense WDM (DWDM) long before it became dominant.
For many serious engineers and students, a physical copy is still the preferred choice. The official publication data for the 2nd edition is as follows:
A critical portion of the text teaches readers how to design a functional system. Engineers learn to calculate power budgets and rise-time budgets to ensure the receiver can accurately decode the transmitted data. Educational Value of the Reference Benefit to the Reader
Gowar, affiliated with the University of London, approached the subject with a rare combination of mathematical rigor and intuitive physical explanation. Unlike many authors who bury the reader in complex Maxwell's equations from page one, Gowar builds a conceptual bridge from the basic properties of light to the sophisticated architecture of a transatlantic fiber link. optical communication systems john gowar pdf
The chapter on receivers is Gowar’s masterpiece. He derives the for PIN and APD receivers from first principles, including:
